Fi- 15., a a detail plan view showing the plunger-rod and intermediate locking-lever. Fig. 16,'isa diagram of the. circuits of thesystem to be referred to. Fig. i 17 is a detailof one of the independent actuators for the transmitter, a

Referring to the drawings wherein I have shown one embodiment of my invention for pur oses of illustration, a represents the shel of the box or case which-is of any suitable size and shape, a. the inner door which is hinged to said shell or case and which serves as a supporting-plate for many of the 0 crating arts, anda the outer door. On t e inner oor the usual telephone set is sup-' ported. On the rear side of the inner door a, a multiple signal-transmitter is located which is contained in a cylindrical case a. 105 The transmitter is provided with what is, ordinarily called a noninterference-,pull by which it is wound up or otherwise operated.

. b represents the actuating-lever of the transmitter which is secured to a short shaft 6 extending through the inner door, see Figs..2 and a said lever being located on the inside of said door. The lever bears a pawl 6 which is ada ted to engage a stud b projectin from t e sector a or other windingq mem er of the transmitter. The pawl is. pivoted to the lever b and is movable into and out of position to engage the stud 6?. When the lever is in'its normal elevated position, .see Fig. 4, the pawl engages a flat spring b by which it is turned on its pivot 1 ,fiat sprin and moved into position to engage the stud, and as the lever is depressed the pawlengages-said stud and remains in engagement therewith by friction, but as soon as downward pressure on the lever is relieved the pawl, is moved immediately out of engage,- ment with the stud by a spring b.- The pawl will be held by the spring b in its outof-use position until-the lever resumes its normal positlon and the pawl again engages the flat spring b". When the lever b is depressed and the awl b has disengaged the ward slig tly by its inherent spring action, far enough for its end to occupy a pop sition back of a detent b which is secured to a pivot-shaft c of the locking-lever for the train, to thereby prevent movement of said locking-lever by the detent engaging the I said lever b is requiredto wind the train and lea with it into the dotted line position shown I in Fig. 4, and at such time it will occupy a flat sprin and not until the lever b resumes 1ts norma osition and lifts said spring I) can the loo ting-lever be moved to release.

the train. Hence downward movement of upward movement thereof to release it. As soon as the spring I)" is lifted by the lever b resuming its normal position the detent 12 is disengaged and the locking-lever permitted to operate.

en the locking-lever is moved to rethe train the detent b will be moved Y position beneath said spring b and will act to hold said spring in its elevated osition.

A lever 25 is alsosecured tothe s aft b, which is located outside of theinner door,

'seeFig. 3, and two actuators are provided for said lever, one for. moving it to move the actuating-lever b a short distance, to. op-' erate' the transmitter one round, and the other for moving it to move the actuating lever b a long distance, to o eratethe transmitter more than one roun as for instance to operate thetransmitter four rounds.

. b" represents one of the, actuators, WhlCh is made as an arm. and which is mounted loosely on the shaft 6 and provided at its outerend with a hand-piecev by which it may be operated, its inner end-portion overs lying a projection on theshort end of the lever b, whereby'downw'ard movement of b, t e latter will move down-' the arm moves said lever 72 and turns the shaft ba short distance. Stop pins 2, 2, on the lnner door limit the movement of said arm. 6 represents a lever which forms a 'part of the other actuator, and said lever is pivoted to the inside of the outer-door,

and has at one end a projection b", which,

when the door is closed, ext-ends under the long end of the lever b. The opposite end of the lever b is connected by a link 6 with the upper end of a slidin bar I), which is mounted on the inside 0 the outer 'door. and which is provided with a hook Z)" which extends outwardly throug1 a slot in the door, so as to be accessible from the exterior thereof. As the hook is'drawn down the lever b is moved onits pivot and the long end of the lever b raised to thereby turn the shaft 5" in the same direction that I it is turned by the actuator Z), but a much longer distance, sufficient to operate the transmitter four rounds. Thus it will be seen that the transmitter may. be operated when the outer door is closed ,to,transmit a number'of rounds of the signal and when theouter door is open to transmit one round of the signal; ,When either actuator is drawn down the actnating-leverb is moved and when let go said actuating-lever is imally from one side of said sector. The sector enga es a pinion c, which. is mounted loose y on a shaft 0, and to one end of said pinion a ratchet wheel a is secured. Said ratchet wheel engages a pawlc pivotally "sting-lever b is fixed to and projects latera mounted on one face of a toothed-wheel 0 I and continuously held pressed into engagement with said ratchet-wheel by a spring 1;". The toothed-wheel a is secured to the shaft 0 and engages a pinion 0 secured to a shaft 0 bearing a toothed-wheel c which engages a pinion 0 secured to a-shaft a, bearing a toothed-wheel 0 which en:

To contro the setting of the train for one or a number of roundsof the signal, a locking-lever is rovided for the train which is controlled y the sector. a

0 represents the locking-lever which is secured to a pivot-shaft 0,- one end of which engages a. detent a secured to the shaft 0", or to some other shaft of the train, and the other end of which rests upon a pin a projecting laterally from the sector a. As the sector is depressed the pin a is removed from beneath the lockingdever and said lever is then permitted to move to disengage the detent a", and is moved by a spring a" which surrounds the pivot-shaft 0 and which is attached at one end thereto, as soon as the detentb is released by the sprin b. Such movement of the locking-lever is limited by a in b which is engaged by the arm I). s the sector returns to its normal position the pin a thereon engages and restores the locking-lever.

Whether the sector is moved a short or a long distance to wind the signaling-train for one or a number of rounds the cooperation of the pin c 'with alarm call shall be transmitted slowly. accomplish this variation in the speed of the the locking-lever is the same, as the moment the pin is removed from beneath said lever, the said levervis .placed under the control of the detent b,

and is subsequently permitted to move, and

not until said pin a resumes its normal position will it be restored.

It is designedv and intended that the oneround or inside signal,"which I have selected as the police-alarm calljshall be transmitted quickly,and-the four-round or outside signal, whlch I have selected as the firetwo signals means are herein provided for varying the speed of the train. The means herein shown consists in the provision of a second pallet a, see Figs. 6, 10 and 12, which is normally disenga ed from the escape-wheel 0 as shown in iig. 6, but which is adapted. to. be moved into engagement therewith whenever it is desired to cause the train to run'slowly. The second pallet acts conjunetively with the the. slow regulating lpvice for the train, while the pallet 0 acting alone serves as the pin travels,

pallet a", to serve as the second pallet is disengaged from the escape-wheel} thetrain will run quickly, being regulated'solely by the quick regulating-degvicect. -Tlie; ivot-shaft 0?, bearing the pallet a has its earings ina pair of arms 0 a, respectively located adjacent the two side plates, and both secured to a having'its bearings in said si e-plates, said arms and the pivot-shaft bearing them constitutin 1a movableframe for supporting saidpa et.

frame with the pallet c disengaged from the esca e-wheel. I The movement of the frame is imited by the stop pins 0", ands, see Fig. 6.

Means are provided, adapted to be operated by the winding-member of the signaltrain. for controlling the movement of the pallet-carryin frame, said means permitting the win ing-m distance to operate t c signaling-train one round without moving the pallet-carrying frame, so that the one-round signal may be transmitted quickly, butcausing the windin -member, when moved a long distance to wind the signaling-train for a number of rounds, to move the pallet-carrying frame so that the pallet will engage the escape-wheel and the train thereby be caused to run slowly during the entire. number of rounds. The means for thus controlling the movement of the pallet-carrying frame consists of an actuating-arm c", loosely mounted on the ivot-s'h'aft a, which is extended upwardly into cngagement'withthe pin a? on the sector, and is curved substantially concentric to the pivot of said sector, and has a cut-away portion near its upper end along which said without moving the arm on its pivot, as the sector is depressed a short distance to wind the signaling-train for one round, and has an engaging-portion extending from the lowerend of said cut'away portion downward for a considerable distance which is engaged pin for the purpose of moving the arm asthe sector is ivot-shaft a the function of said spring being to hold the I mber to move a short depressed a long distance to windtlie signaling-train for a number of rounds. VJ

A spiral spring 0*" surrounds the pivotshaft 0 which is connected at one end to the actuating-arm a and atthe other end to the arm 0 of the pallet-carrying frame, and elastically connects said arm 0 with the pallet-carrying frame, whereby said frame is i the pallet in engagement with the escape-- which is employed. or this purpose,which,

i side of the plunger-rod f for convenience is mounted loosely on the pivot-shaft 0 beside the locking-lever, it

1 being here n shown as a bell-crank lever, one arm of wh1ch extends over the pm 0 and is provided at its end with an engaging portion which. is adapted to engage the arm 0?, and

the other arm of which extends up alon of the box, which latter is designed to bermoved inward longitudinally by the closing. of the box-door and to, be thrust outward by a spring-when said 7 door is opened.

a lever e has a notch at its ,The up er end of the arm a. has a notch at one si e and the outer end of the detentunder side, and when the arts areatfrest, seeFig'. 11, and the lever 1s held in its elevatedposition by the pin 0, it extendsoverthe end of 'the arm and enters the notch therein, and when the pin 0 is moved from beneath the lever by depression of the sector, and the arm 5 2 is moved by said pin a, see Fig. 10, said selected as the" police-ca report call, -and the signal ,is simply "the box-number. which is'transmitted by breaking the. circuityfor short report-call, as for instance,

' both important means are provided whereby a difi'erentiating impu 1 lever is permitted to move downward, and is so moved by aspring e which is attached to it, the'end of the arm entering the ,notch'in' the lever. The lever e is finally restored to its normal elevated position by the pin a, which engages 1t on thereturn movement-of the sector." The lever a, when once depressed, operatesto hold the arm as until restored by said pin,"and while said arm is-so held by the lever,'-t-he pin will travel over its cut away portion,;and all the rounds of the signal will be transmitted slowlythe second palletengaging the escape-whee 4 :The-one-round fast si nal, which is herein is emplcyedas the periods of time. For police-signaling purposes, howeve other signals are quite as important'as-the the telephonecall. and wagon-call, hence -I have provided means whereby these two extra calls may be As these two-gextra' calls are lse may accompany them in order that they'mayabe readil distinguishedfrom'the' report-call. The ifi'er ent atingeim-pulsemay be simply a'lon breakin the ClIClllt as contrasted with" the l "short breaks of the report-call.

The means, herein shown for providing plate and which -is sec'ured to the. ivot-shafb is moved outward- The intermedia? ed r for the transmission of the extra calls con-'- sists in providing the signaling-train with an intermediary locking-device, whichis adapted to stop the train when the 'boxnumberor report-call has-been transmitted, but before the signal-wheel has completed its round, and in providing means for open ing the circuit for a long period of tune, Y which is adapted to be operated by said train when said intermedlary locking-device is operated to release it while the door of the box is still open. The diflt'erentiatingimpulse thus transmitted, .followin the box I number produces the tele hone-cal Means are also rovided for re easing said intermediary coking-lever by the'act of pulling the box a second time while the box door is stillopen, the diflerentiating-impulse being then transmitted, and the box-ni1mber repeated, following) said diflerentiatin -impulse, such call eingthe wagon-cal and being readily distinguishedfro'm theother calls by the difierentiating-impulse being arranged between the two box-numbers.

9 Figs. 6, 13 and 14, represents the intermediary flocking-lever which is mounted loosely on the pivot-shaft g", and has its enga ing end arranged to engage the 'detent 0 o the signaling-train. It'is moved into its locl ing position 'by the spring e, which is attached to it, when said s r ng is permitted to act, and it is moved plunger f, and by means controlled by the removal of the telephone from its support, and by means 0 .erated by pulling the box, these several di erentjmeansfor moving it being employed at difi'erent times-and under diiterent conditions. As the intermediary lockln -lever is used only in connection Wit the fire-call is being transmitted, and as the policecalls are all transmitted when the box door is open and the fire-call when the box door is closed the plunger f is employed'to move the intermediary flocking-lever into and to hold it in its unlocking p the box door is closed, permittm The 'plunger, f hasa collar f formed a beveled end f which is'adapted to engage an inclined ortion f on an arm. j which is r bent to pro ect through ahole int-hesidei Inward movement of the. p unger operates to raise sa1d arm'against the tension of a? spring f, Fig. '5,'.which latter acts to'f when the plunger draw the arm downward 100k ing-lever g has-a pin 9? extend om it which extends; over the arm if, as said arm is raisedby t e into its unlockingposition, as herein shown, by the 10's the po ice-calls it is held out of action while ositionwhen g it to move into its locking position-only w en the box door is open. 115.

plun er th M locking-lever 9' will be raised out of t e path of movement of the detent 0 ?,and when the 30 movement of said detent.

arm descends r he locking-lever will be caused to occupy a position in the mth of Y Thus w en the box door is closed the intermediary lockinglever is positively held out of action by the plunger and'is permitted to operat only when the box door is open. The intermediary locking-lever has also projecting from it a lug g, which extends through a hole in the side plate, which is adapted to be engaged by means operated by the tele hone-support when the telephone is remove therefrom to thereby raise the intermediary locking-lever, Figs. 2 and 7 As herein shown, a bar h is supported vertically near one of the side plates which rests by gravity u on the pivoted supporting-"arm h for the to ephone, and .said bar has fixed to it, near its upper end, a collar h which projects beneath the lug on theintermediary locking-lever, and when the telephone is removed from its support and said sup ort thereby. crmitted to rise said bar will is corres ingly raised and by its engagement with tne intermediary locking-lever will raise said lever and therebyremove it from the path of engagement with the detent 0 The intermedlary locking-lever g also has an extension g provided with a curved engaging-portion, see Figs. 6 and 14, which extends down alongside of the sector a, which is adapted to be engaged by a pin a on said sector, as the latter is depressed, to thereby move said locking-lever into its unlocking position to release the train.

The pin 0 disposed at short distance from the extension g, so as not to enga e it immediately the sector starts downwar in fact, not until the sector has been moved downward and almost tar'enough to wind the train for one round. If the intermediary locking-lever is in its unlocking position when the sector is depressed then the pin 1"" will not engage the extension g".-

To proyide for transmitting the difi'er- 'entiatlng-nnpulse the signal-wheel d has projecting om it a pin 4', which at times can engage an. arm (1 loosely pivoted to the end of the plunger-rod f, and moves said arm on its pivot for a period of time that the pin engages it. The arm d is forked to receive a pin (i projecting from the signaling-lever d, and as it is moved on its pivot by the pin on the signal-wheel said signaling-lever will, therefore, be moved to operate the circuit contacts.

The pin (1 on' the signal-wheel is made quite short and the arm d which it engages, being supported on the plunger-rod, is movable by said rod toward and from said pm,

in the direction of its length, so that when the plunger-rod is thrust lnward by closing the box door srid'arm will be moved beyond the path of engagement with said pin, :uid in such case the signal-wheel will complete stopped by the intermediary to swing out by plete its roninl without operating said arm, but when the plunger-rod is in its outermost position, the door being open, said arm is brought into position to be engaged by said pin. The means for effecting the transmission of the differentiating-impulse is, therefore, controlled by t-he plnnger-rod, which is controlled by the box door, and will be set to transmit said im ulse only when the box door is open, WlllC it will be understood is when the fast or police calls are I being transmitted.

When the fast-call is'transmitted, the box door being open, the train will be'stopped by the intermediary locking-lever as soon as the box-numberhas been transmitted, and when only the report-call is desired to be sent the box door will then be closed,.and v upon closing the door the plunger Wlll be thrust inward, the arm d moved out of the path of movement of the pin d and the intermediary locking-lever raised to release the train, permitting it to run and complete its round.

When it is desired to transmit the telephone-call the fast-call will be transmitted and the telephone removed from its support, and said locking-lever will thereby raised and the train permitted to complete its round, during which time the differentiating-impulse will be transnntted by the pin .llflengaging the arm (i Vheirit is desired to transmit the wagoneall the fast-call will be transmitted and the signaling-train stopped by the intermediary locking-lever. The actuator" will then be )ulled a second time, thereby again operating the winding-member 0, and the pin c thereon will engage the extension 9 on said locking-lever and will move the lockinglever into its unlocking position and release the train. 011 the return movement of the winding-men]ber the differentiating-impulse will then be transmitted, and the train will continue running for another round, the boxnumber will be again transmitted and the pin a", will disengage the extension 9, and

the signalin -train willbe again stopped by the interme iary locking-lever. .Upon closing the box door the arm (I will be moved out of the path of the pin J and the intermediary locking-lever will be moved by the plunger into its unlocking position and the train thereby released and permitted to comits operation. WVhcn the tram 1s locking-lever the winding-member has so nearly returned to normal position that the pawl b on the lever b, so that, when said lever is a second time depressed, the pawl will engage the pin 7) before it is permitted disengagement with the spring I). The wagon-call thus transmitted will comprise two box-numbers and a differentiating-impulse l'ietween them. Thus the pin I) is close to' the telephone-call and the wagon-call each include a diflerentiatlng-impulse.

When the door is closed and the plunger,

- thrustinward and the arm d moved out of 5 thepath of movement of the pm (Z and the outside or fire-call is bein transmitted, if at such time the box dOOISTlOIlld be opened, inadvertently, the plunger Would, unless prevented, be thrust outward and the arm 01 moved into position to be engaged-by the pin (P, and a lon break be transmitted with the fire-call whici would confuse it, and to obviate this, means are provided for preventing the plunger moving outwardly at such time.

Referringto the detent-le'ver 6, see Figs. 6 and 10, the arm of said lever which extends up alongside of the plunger-rod f, -is-normally held out of engagement with said rod by the other arm of the detentlever engaging the pin 0'" on-the sector a, but when said sector is wound the lever e engaging it descends first upon the arm a and as the sector is further wound the pin 0 engages the, raised-portion o'f-lever 0 swin mg the same on its pivot to the ri ht and trom beneath the lever e and allowmg said lever e to further descend and its. up-

wardly'extended arm is also moved toward the plunger-rod, into a position backof the collar f on said rod. Incase the box door should be opened at such time the plunger is revented from moving outwardly by the end of the collar f thereon engaging the side of the arm. When the parts resume their normal positions the arm 6 is restored by the pin 0 on the sector just before it runs down.

ing-im ulsew In my Patent #898,095, dated Sept. 8th, .1908, an intermediary locking-device is rovided for arresti'n the signaling-train u lien one of the signafis has been transmitted, which is adapted to be moved into its unlocking position to release the train and permit it to continue its' operation and transmit a different signal; also, in said ap lication the intermediary'locking-device'is a apted to be moved into its unlockingposition by 'means connected with the telephone-support, whereby, upon the removal of the telephone vfrom its support said lever may be moved and the train released and permltted- .to continu'e its operation to transmit a dif ferent signal; also, in said application the intermedlary locking-device is adapted to be moved into its unlocking position by closing the box door; therefore these features are not herein broadly claimed.

. .z' and i, see Figs. 8 and 9, represent a pair of spring-acting contact-pens which are respectively connected to the wires of'the Hence .even if the -box door should be opened while the fire-signal is. being transmitted the signal can not be confused by the transmission of the difierentiatnain circuit n, which is herein represented as ametalllc clrcuit having a battery n, and said pens are normally in engagement by ing from the middle of said said contact-pen is adapted to be engaged by the contact-pen z" to connect it with the main circuit a. Y I

The contact-pen z" is provided with a hook i, which extends over the end of the contact-pen 2' and said pen '5 is provided with side by the contact-pen z" and at the opposite side by the hook '5 -The pen & normally occupies a position midway between the pen 2'" and hook 2', so that the secondary circuit is normally open.

The supporting-block bearing the pen 2' is made movable, so that the pen borne by it .may be moved into engagement with the block it is attached to a plate 2", which is 0 of the movable pallet-bearing frame. By

Withthe frame, and as said frame is'moved only when the slow-signal or fire call is bein transmitted it will be seen that said pen a will only be moved into engagement with the. hook atsuch time. At all other times When the pen 2' has thus been moved into engagement wit-h the hook i movement of the pen z" by the signal-wheel separates the main contact pens 2' and z",-and also separates the hook from the contact pen 2' thereby breaking boththe main and secondthe pen 2' remains-in its normal position, movement of the pen 2' by the signal-wheel separates the main" contact pens z" and i, but first closes the pen 2', with the pen thereby first connecting the main circuit with the secondary or ground circuit and thereafter breaking the main circuit at one side of the grounded place only.

The main circuit n, at one side of the battery n, is provided with a signal-receiving relay n and with the usual telephone set, which is .represented at n, and at the opposijte side of the battery is provided with a p i represents another spring-act' ingcontacfipen which is connected to a seemay be a ground hook 2', and to provide for moving said" formed integral with or attached to the armattaching the supporting block of the pent to said pallet-bearing. frame, itwill be moved said pen remains in itsnormalposition.

ary or ground circuits simultaneously. When signal-receiving relay n and with a gong n,

running parallel to the circuit 11. and leadbattery; and

a double contact so as to be engaged at one and one of said relays, as n for instance,

may be employed particularly to operate the recording instrument. for recording the fast: signals for police and the other relay, as a, may be employed particularly to operate the recording instrument for recording the slowsignals for fire. In practice a double. pen register may be employed which is adapted to be operated or controlled by said relays. The contact pens z of all of the boxes in the circuit will be arranged to be connected to the same side of the main circuit, so that the relay between said boxes and the battery, on that 'side of the line will be effected by said pen in operating.

When transmitting the slow-signals or fire-call the pen 5 is moved into'engagement with the hookz' thereby connecting it with the main circuit a before the main circuit is broken for the first tune by. the signal-wheel, .as represented; at box marked'41, then as the signal-wheel'revolves said secondary circuit is opened and closed in unison with the main circuit, and the signal is received on both relays.

In case the main circuit is broken when the box is pulled the signal would then be received over the unbroken side of the main circuit and the secondary circuit, and the relay on that unbroken side of the main circuit would receive the signal. In case the slow-signal of two boxes were pulled at the same time there would be'no loss of signals, as one signal would be transmitted correctly over oneslde of the mam circuit and the secondary circuit, and the other signal would f its slow-signal, the second box would lmmebe transmitted correctly over the other side of the'main circuit and the secondarycircuit, and both signals would be received and recorded on the recording instruments on their respective sides.-

If a second box was pulled for the slowsignal while another box was transmitting diately take control of the receiving apparatus at its own side'of the main circuit, and would add its signal to that portion of the signal already received by the first box on that side ofrthe line, but it would not interfere in any way with the proper reception of the first signal on the opposite side of the circuit.

\Yhen transmitting the fast signal or police-alarm the pen 2' will remain in its normal position, as represented at box' .marked 23, or the one marked 32, then as.

the signal-wheel revolves the pen 2" will not be engaged by the pen z" until the latter has been moved slightly and just before it disengages the pen i.

The closures of the sc- .ondary circuit will. therefore, be only momental-y during the transmission ofthe signal and each closure will be ust long enough to keep the fire-alarm side of thecircuit other ast-signal was being signal would be remote.

two of t e .quick closures through closed on each break. This arrangement will permit the fast-signal to be transmitted over either side of the main circuit in emer gcncies such as a broken line, and further more it gives the least possible chance for interference of police-signals with the more important fire-signals, the danger of which or of added complications to prevent such, having been one of the strong objections to a combination police and fire-alarm system. The fast time of the police-signals has also in practice been found to reduce the chances of an'interference between police-signals to a minimum. I

The complete police-si nal requires but three or four seconds, an as the telephone receiverof a box is cut into circuit when the box door is open as will be hereinafter described, the ofiicer at the box desiring to transmit a signal could readily hear the clickinof the'telephone in the box if antransmitted and therefore could wait at most but a fewseconds for the first signal to be completed when he could thereafter send his signal.

As the fire-signal is slow lts breaks in the circuit are of necessity long, and as the fastof short breaks, accomsignals are composed of long duration,
